Parameter Symbol Test Conditions Min Typ Max Units Output Voltage Accuracy ΔVOUT IL = 1mA, VIN = 5V -2 -- +2 % Output Voltage Temperature Coefficient -- 50 150 PPM/ °C Line Regulation ΔVLINE IL = 1mA, VIN= 4.5 ~ 12V -- 2 3 %VOUT Load Regulation (Note1) ΔVLOAD IL = 1mA ~ 300/500mA, VIN = 5V -- 1 30/50 mV RT9161 350 580 -- Current Limit (Note 2) RT9161A ILIM VIN= 5V, VOUT = 0V 500 900 -- mA Dropout Voltage (Note 3) VDROP IL = 300/500mA -- 450/750 600/1000 mV Standby Current ISTANDBY IL = 0, VIN = 12V -- 110 180 μA Note 1. Regulation is measured at constant junction temperature, using pulsed ON time. Note 2. Current Limit is measured at constant junction temperature, using pulsed ON time. Note 3. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV. Note 4. θJA is measured in the natural convection at TA = 25°C on a low effective single layer thermal conductivity test board of JEDEC 51-3 thermal measurement standard. |
